TELESCOPE-MOUNTING FOR GUNS.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed February 14,1907. Serial No. 357,387.

To all whom it may concern:

Be it known that I, JOSEPH WILKINsON, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Telescope- Mountings for Guns; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to telescope mountings for guns, and consists in certain arrangements of parts and combinations of parts as will be hereinafter fully described and then particularly pointed out in the claims which conclude this specification.

My present invention is an improvement in the construction shown and described in Letters Patent No. 834,785, issued to me October 30, 1906, and relates solely to a novel manner of adjusting the elevation of the telescope to a correct sighting position.

In my patented construction above referred to, I employed a single sleeve around the telescope to which sleeve the rear link was pivoted, in combination with a securing lever, the operation being such that when the lever was raised the band could be forced along the telescope barrel to an adjudged proper position, and then held in this position by throwing the lever down. This manner of adjusting the elevation of the telescope has been found crude and unsatisfactory, because frequently the lever must be operated several times and the sleeve moved back and forth until the correct elevation of the telescope was obtained.

The object of my present invention is to provide accurate adjustment which may be arrived at while the eye is at the telescope, while at the same time adjustments for widely different ranges may be made with great facility.

In the accompanying drawings Figure 1 is a side elevation of a gun equipped with my improvement Fig. 2 a partly broken and sectional elevation of the telescope and the adjusting mechanism, and Fig. 3 a view similar to Fig. 2 but showing a slight modification.

Similar numbers of reference denote like parts in the several figures of the drawing.

1 is the telescope, 2 a sleeve around the rear portion of the latter and capable of sliding freely thereon, 3 a sleeve clamped around the front portion of the telescope, and 4, 5, are links pivoted about midway of their lengths to said sleeves respectively, the bottom extremities of these links being provided with inwardly projecting teats (not shown) which are sprung within sockets (not shown) in the frame 6 and barrel 7 of the gun, so that these links are capable of a free swinging action. I will not enter into any further or detail description of the manner of mounting the telescope since this forms no part ofmy present invention, and is, moreover, fully set forth in my Letters Patent above referred to.

In the rear of the sleeve 2 is another sleeve 8 which is clamped to the telescope barrelbymeans of the thumb screw 9.

Both the sleeves 2 and 8 have inwardly extending right and left handed threaded portions 10, 11, and loose around the telescope barrel is a knurled collar 12 interiorly threaded at each end and engaging the threaded portions 10, 11. The forward part of this collar has graduations marked preferably 1, 2, 3, I, 5, 6, 7, 8, 9, 0, (only the graduations marked 7 and 8 appearing in the drawing) and these register with the arrow on the sleeve 2 when the collar is turned around.

By turning the collar around with-the thumb, while the eye is at the telescope, the sleeve 2 will be thrust forward or drawn backward, thereby raising or lowering the link 4, whereby the proper elevation of the telescope may be accurately and quickly obtained.

In case it becomes necessary to sight for a widely different range, the thumb screw 9 is loosened and the sleeves 2, S, and collar 12 then shifted bodily along the barrel of the telescope toaposition determined by one of the graduations l3, whereupon the screw 9 is tightened, and the further correction of the sighting effected by turning the collar 12. These graduations 13 are for widely different ranges, generally speaking, and may be marked from one hundred feet up to twenty five hundred yards or more, and they provide merely for approximate adjustments readily made by shifting the sleeves and collar bodily, the finer and correct adjustments being effected by afterwards operating the collar.

It is, of course, not necessary that the clamped sleeve 8 should be in the rear of the sleeve 2, although I prefer this arrangement since it is more convenient and ready of manipulation than the reverse arrangement with the clamped sleeve in front of the sleeve 2. Also, it will be clear that in effecting'the adjustments of the telescope, it is merely necessary that the turning of the collar should move the sleeve 2 back and forth as the occasion may require, and therefore a small pin 14 may extend inwardly from the collar within a groove 15 in the extension 11 of the sleeve 8, whereby the collar may be swiveled to one of the sleeves and engaged with a threaded extension of the other sleeve as shown 'at Fig. 3, but I prefer the construction shown at Figs. 1 and 2, since it possesses greater stability and is therefore better adapted to I withstand the shock incident to the firing of the gun.

It will thus be seen that I have actually provided a micrometer adjustment for sighting the telescope while the eye of the shooter is at said telescope, while at the same time the sleeves and collar used to obtain the adjustment are disposed on the barrel of the telescope concentric With the axis thereof, an arrangement not only exceedingly convenient but possessing marked advantages so far as ready manipulation and quick results are concerned.

I claim:

1. The combination with a gun and telescope, of two links pivotally supporting the telescope on the gun and arranged near the ends 01? the telescope whereby the latter has a free longitudinal swinging movement, the two sleeves tight sleeves around the telescope barrel the rear link being pivoted to the loose sleeve, and a collar loose around the telescope barrel and connected at its ends with said sleeves in such manner that rotary movements of said collar will cause said loose sleeve to be shifted to elevate or lower the telescope.

2. The combination with a gun and telescope, of two links pivotally supporting the telescope on the gun and arranged near the ends of the telescope whereby the latter has a free longitudinal swinging movement, the two sleeves around the telescope barrel and having facing screw threaded portions, and the threaded collar which engages each of said threaded portions, one of said sleeves being loose on the telescope barrel and pivoted to the rear link while the other sleeve is provided with means for temporarily clamping it to the telescope barrel.

3. The combination with a gun and telescope, of two links pivotally supporting the telescope on the gun and arranged near the ends of the telescope whereby the latter has a free longitudinal swinging movement, the sleeve to which the rear link is pivoted said sleeve being loose around the telescope barrel and having a threaded extension, a second sleeve clamped around the telescope barrel in proximity to the first named sleeve and having a threaded extension, the threads on said extensions being of opposite natures, and the collar loose around the telescope' barrel and having its ends threaded interior-1y and engaged with said threaded extensions.

In testimony whereof I ailix my signature in presence of two witnesses.

JOSEPH WILKINSON.
